SCIENCE SUNDAY
1 The James Webb Space Telescope found a black hole wrapped inside a star-like cloud of hydrogen, producing energy no known star could physically generate.
The object dates to a few hundred million years after the Big Bang and appears to be a black hole encased in a glowing hydrogen shell, producing roughly 100 billion times more energy than any known star could generate on its own. MIT scientists have dubbed it a "black hole star," a genuinely new category of astrophysical object rather than a variant of something already catalogued. Finding an entirely new class of object, rather than a new example of a known one, is the rarer and more significant kind of discovery, and this early in the universe's history makes it more significant still.
2 An experimental Chinese bullet train hit 800 kilometers per hour in 5.3 seconds, as fast as a commercial jet's cruising speed.
A test vehicle at China's East Lake High-Speed Railway Lab accelerated from zero to 800 km/h in 5.3 seconds, theoretically fast enough to travel from New York to LA in roughly five hours by rail. It is the third world record broken at the same facility since 2025. The lab's ultimate target is 1,000 km/h, and at this rate of progress, it looks genuinely on track to get there rather than chasing a distant, speculative goal.
3 A new treatment fully cleared an HIV-like virus in infant primates when no single therapy could do it alone.
Scientists at Oregon Health & Science University found that combining standard antiretrovirals with two experimental antibodies, given within three days of exposure, fully cleared HIV in newborn primates, something none of the treatments achieved individually. The regimen could head to human trials soon. With more than 120,000 babies infected with HIV each year, a working human version could spare a meaningful share of newborns a lifetime of daily medication.
4 A self-powered offshore vessel could bring electricity, clean water, and AI compute to disaster zones within days, with no fuel or emissions.
Optimal Transit unveiled a second configuration of its Kraaken vessel, a self-powered offshore platform expected to generate 40 MW of baseload electricity and produce fresh water for 150,000 people, entirely without fuel or emissions. The $587 million vessel is designed to disconnect and relocate within hours, which could make critical infrastructure meaningfully easier to deploy in disaster zones and regions with unreliable grids, where the usual bottleneck is not the technology but how long it takes to physically get power on-site.

Five things people are actually watching and sharing
🌑 Lights out. Europe just witnessed its first total solar eclipse in 27 years, producing breathtaking and now viral images of the Sun's glowing corona. But the view from space might be even more surreal.
☀️ Solar blockbuster. If you missed this year's eclipse, next year could offer an even bigger spectacle. The "eclipse of the century" will plunge parts of Europe, Africa, and the Middle East into darkness for more than six minutes next year. With prime viewing spots already filling up, this guide shows you where you can still catch it.
🦠 Tiny terror. It looks like something dreamed up for a sci-fi horror movie. This terrifying microscopic animal looks like it has a rotating chainsaw for a mouth as it pulls bacteria and algae in for dinner (2.9M views).
🥤 Bottle buster. A glass Coke bottle looks fragile, but it can handle far more pressure than you might expect. This satisfying experiment keeps piling on the weight until it finally gives way.
⚓ Ancient survivor. More than 2,400 years ago, an ancient Greek merchant ship sank to the bottom of the Black Sea. Thanks to one extraordinary quirk of its resting place, it is still remarkably intact today. See the shocking wreckage. (28,000 likes)
